Answer:
the correct option is E. d is biased.
Step-by-step explanation:
As given,
The expected value of d hat is not equal to D.
We know that,
The unbiased-ness is the property that tells the expected value of d is equal to D
So, the correct option is E. d is biased.
12x12=144+144-88=200 good luck!
Answer:
-2 3/4 < -1 1/2
Step-by-step explanation:
Positives are always greater than negatives (Example: 2 is greater than -2).
This eliminates the first and last inequalities.
Smaller negative numbers are always greater than larger negative numbers (Example: -2 is greater than -4).
This eliminates the third unequality.
For the second given inequality, convert the fractions to share the same denominator.
-2 3/4 < -1 2/4
They are both negative numbers.
We know smaller negative are always greater than larger negative numbers.
This inequality aligns with this statement.
Therefore, only the second inequlity is true.
Answer:
Option A. 8x² - 25x + 7.
Step-by-step explanation:
The given polynomials are
A = 3x -4
B = x + 7
C = x² + 2
Now we have to find the simplest form of A² - (B + C)
A² = (3x - 4)² = 9x² + 16 -24 x
B + C = x + 7 + x² + 2 = x² + x + 9
Now A² - (B + C) = 9x² + 16 -24x -(x² + x + 9)
= 9x² -24x + 16 - x²- x - 9
= 8x² -25x + 7
Therefore Option A. 8x² - 25x + 7 is the answer.
